Good Wife Exclusive: Michael J. Fox Returns!

Sunday night’s installment of The Good Wife found Christine Baranski’s Diane Lockhart cracking a joke about raiding the law firm of rival Louis Canning (Michael J. Fox). But perhaps there was a little bit of truth in her zinger.

TVLine has learned exclusively that Fox is returning to CBS’ Sunday-night drama for the eleventh episode of Season 4, which will likely air in January 2013.

The actor last appeared on The Good Wife during its Season 3 finale, when Canning and competitor Patti Nyholm (Martha Plimpton) teamed up on a case with a broader eye on stealing one of L/G’s biggest clients, a ruse that proved successful and exacerbated the firm’s financial crisis. Fox scored Emmy nominations as Outstanding Guest Actor in a Drama Series for his Good Wife role in 2011 and 2012.
